IbvMemoryRegionView

Struct IbvMemoryRegionView 

Source 
pub struct IbvMemoryRegionView {
    pub virtual_addr: usize,
    pub rdma_addr: usize,
    pub size: usize,
    pub lkey: u32,
    pub rkey: u32,
    pub device_name: String,
    /* private fields */
}
Expand description

A cloneable handle to a slice of registered memory: the keys and addresses a peer needs, plus an Arc<dyn IbvMemoryRegionKeepalive> keepalive.

Cheap to clone; every clone shares the same guard, so the backing registration stays alive (and registered) until the last clone drops.

Fields§

§virtual_addr: usize

Virtual address in the local process address space.

§rdma_addr: usize

RDMA address, possibly offset from the region’s base MR address.

§size: usize§lkey: u32§rkey: u32§device_name: String

Name of the RDMA device the view’s protection domain is on.
